Insights

Modern life disrupts our internal body clocks, increasing cardiovascular disease risk. This review explores how circadian disruption impacts kidney disease, suggesting potential new therapies.

Area of Science:

  • Chronobiology
  • Nephrology
  • Cardiovascular Medicine

Background:

  • Circadian disruption, a misalignment between internal biological rhythms and the environment, is linked to increased cardiovascular disease risk.
  • Cardiovascular disease is a leading cause of death, with kidney disease posing a significant public health challenge and contributing to cardiovascular mortality.
  • Existing treatments for kidney disease are insufficient, highlighting the need for novel therapeutic approaches.

Purpose of the Study:

  • To review current evidence connecting circadian rhythm disruption with renal impairment in humans.
  • To focus on the impact of circadian dysfunction in chronic kidney disease, lupus nephritis, hypertension, and aging.
  • To identify knowledge gaps in the mechanisms underlying circadian dysfunction in kidney diseases and explore potential therapeutic interventions.

Main Methods:

  • Systematic review of epidemiological and clinical studies.
  • Analysis of data linking circadian rhythm disruption to specific renal conditions.
  • Identification of mechanistic pathways and therapeutic targets.

Main Results:

  • Epidemiological data strongly associate circadian disruption with an elevated risk of cardiovascular disease.
  • Circadian dysfunction is implicated in the pathophysiology of chronic kidney disease, lupus nephritis, hypertension, and age-related renal decline.
  • The relationship between circadian rhythm and kidney disease is bidirectional, with mutual influence on disease progression.

Conclusions:

  • Circadian rhythm disruption is a significant factor in the development and progression of various kidney diseases.
  • Understanding the bidirectional relationship between circadian dysfunction and renal pathophysiology is crucial for developing effective treatments.
  • Circadian rhythm-based therapies hold promise as a novel treatment strategy for renal diseases.

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Introduction to Urinary System01:13

Introduction to Urinary System

The urinary system consists of two kidneys, two ureters, the urinary bladder, and the urethra.
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

Physiology of the Genitourinary System I: Renal Blood Flow and Glomerular Filtration

The kidneys are vital organs responsible for regulating blood filtration, waste excretion, and fluid balance, all of which are crucial for maintaining homeostasis. Renal physiology examines renal blood flow, glomerular filtration, and urine formation, ensuring the body’s internal environment remains stable.Renal Blood FlowThe kidneys receive about 20-25% of the cardiac output, typically around 1200 mL of blood per minute in an average adult. Blood flows into the kidneys through the renal...

Factors Affecting Renal Clearance: Renal Impairment01:17

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
